Tech Tip: Timers, Timer Tables, and Rollover

How do you use timers in PAC Control?

If you have a lot of timers, would a timer table be a cleaner way to handle them?

How do you avoid getting tripped up when a timer rolls over, like it does when you use the command "Get Seconds Since Midnight"?

And what if the power goes off while you're timing; have you accounted for that possibility in your logic?

A lively timers discussion recently in the OptoForums delved into all these questions. OptoEngineer Mary St. John offers code for a timer table, and OptoFans chime in with caveats, suggestions, and even a music video.
